Temperature and ventilation

The temperature setting range is +20 °C to 80 °C with a setting accuracy of 0.1 °C. The two built-in temperature sensors are used for monitoring and function takeover in the event of a fault. Convection is provided by natural ventilation.

Control technology

The ControlCOCKPIT with TwinDisplay contains an adaptive multifunctional PID microprocessor controller with two high-resolution TFT color displays. Language settings can be made in German, English, Spanish, French, Polish, Czech and Hungarian. The integrated timer with digital reverse clock can be set from one minute to 99 days.

With the SetpointWAIT function, the process time is not started until the set temperature is reached. A helpful calibration function allows you to set three freely selectable temperature values. The temperature can be set in both Celsius or Fahrenheit. In addition, parameters for program run time, time zones and summer or winter time can be set.


The integrated logging function ensures that the program sequence is saved – even in the event of a power failure.

With the help of the AtmoCONTROL software, programming as well as managing and transferring programs can be carried out via an Ethernet interface or a USB port.

A high level of safety

The temperature is monitored with the mechanical temperature limiter TB protection class 1 (DIN 12880) with heating shutdown approx. – 20 °C above the maximum cabinet temperature.

Both a temperature selector monitor (TWW) of protection class 3.1 and a temperature selector limiter (TWB) of protection class 2 can be selected on the display.

The Memmert AutoSAFETY offers an additional integrated over- and under-temperature monitoring ("ASF"). This automatically follows the setpoint at freely selectable intervals. The alarm is triggered when the temperature exceeds or falls below the setpoint. The heating is switched off automatically when the temperature exceeds the setpoint. The alarm is visual and audible.

A self-diagnosis system is installed for fault detection.
